Laura is the product of a different section of Weapon X. She was cloned from Wolverine's damaged DNA - from the salvaged part of his X chromosome - and born to Sarah Kinney, her mother and the scientist who made her birth possible. Since she could walk, she was trained to be the perfect replication and killer of Wolverine. Under Wolverine and Gambit's guidance, she has since 'found herself'.

Romulus?

It's been clearly stated in Wolverine Origins that Romulus has major plans behind Wolverine and his son Daken, so does this mean if he has any plans for X-23? I haven't heard much, but being a clone of Wolverine must mean something for the plans that Romulus has laid out, right?
